TECHNICAL FIELD

The present disclosure relates generally to equipment for snow sports. Specifically, the present disclosure relates to support and suspension assemblies for riders of a snow sports board.

BACKGROUND

Skiing, snowboarding, and sledding are snow sports enjoyed for recreation and competition in many countries around the world. Skiing and snowboarding involve descending snowy terrain in a standing position with the rider's feet attached to the skis or snowboard. Sledding, by contrast, involves the rider descending a snowy hill while sitting, kneeling, or lying on a sled with no particular attachment to the sled other than the rider's grip. In yet another winter activity, some use a kayak to descend a hill covered with loose snow while using a paddle to make turns, much like is done in whitewater.

DETAILED DESCRIPTION

Disclosed are assemblies and components of a support assembly for use with a snow sports board, such as a snowboard or ski. The support assembly is configured for use by a rider in a seated or kneeling, face-forward position. In accordance with some embodiments, the support assembly includes a seat and a suspension assembly that includes a shock absorber disposed between the snow sports board and the seat. For example, the assembly includes a frame with an inverted-L shape. A shock absorber is connected to the downward-extending portion of the frame and the seat is mounted on the rearward-extending portion of the frame. The frame is connected to the board by the shock absorber and by linkages extending between the frame and a base mounted to the board. The suspension assembly enables the rider to ride the board in a seated, face-forward position with the rider's knees forward of and lower than the rider's hips. For example, the rider may position the knees on a knee platform with support plates on opposite sides of the suspension assembly and positioned below the seat. In some such configurations, the rider's feet can rest on a foot support below the seat or can remain suspended over the board. In another example, the rider's feet are placed on a foot peg or foot support attached to the board or to a rear portion of the support assembly.

In accordance with some embodiments, the support assembly facilitates the user in transferring weight to the board to initiate and make turns on a snow sports board while in a seated or kneeling, face-forward position. The rider's height above the board can be used for leverage during turning. For example, the rider's center of mass above the board enables the rider to use the support assembly as a lever to put the board on edge. In skiing, the skier's legs and knees act as a shock absorber to absorb centrifugal forces generated during a turn. Similarly, on a snow sports board, the centrifugal force acts on the rider towards the board, but since the rider is not in a standing position on the board, the legs and knees are not used in the same way to absorb the centrifugal force. The suspension assembly is generally configured to dampen vibrations and to absorb and reduce the impact forces to the rider associated with bumps, jumps, and centrifugal force generated during turns, for example. The suspension assembly may also help the rider transfer centrifugal force to forward momentum, and therefore speed, when coming out of a turn.

In accordance with some embodiments, a combined support and suspension assembly is configured to enable the user to board a chairlift while in an active-use position, such as when the rider is seated on the seat with knees (and/or part of the lower leg) on a support platform. For example, the portion of the frame supporting the seat is cantilevered above the board at a height to receive a chairlift seat in the unobstructed region below the seat. The rider may board a chairlift without modifying or changing the configuration of the suspension assembly and may board the chairlift in an active-use position with the seat of the support system on top of the chairlift seat. Numerous embodiments and variations will be apparent in light of the present disclosure.

General Overview

Snow sports boards, such as snowboards and skis, are commonly ridden by the user in an upright, standing position. For a different experience similar to whitewater kayaking, some users desire to ride a snowboard or other snow sports board in a kneeling position. One approach has a shallow platform mounted to the snowboard and shaped to accept the rider's knees. The platform situates the rider in a kneeling position on the board with the feet in a downward-pointing position below the rider's body. Such a device has been found to be inefficient in transferring the user's weight to the board, therefore making it difficult to control of the board. Further, the rider's position on the board has been found to be uncomfortable generally, and painful after extended use due to the forces exerted on the rider's feet and ankles.

Another approach is the sit ski, which was developed for the adaptive community, such as those who may not have use of the lower body. The rider of a sit ski has a face-forward, recumbent position with the rider's hips retained in a bucket-style seat and with the rider's knees and feet extending in front of the rider. The seat is attached to a ski using a traditional binding, where the seat assembly occupies the position normally taken by a ski boot. To achieve a low center of gravity, the rider's hips are positioned vertically below the knees with the upper leg (e.g., femur) extending upward from the hip to the knee. In some cases, the rider's knees are close to or actually contact the rider's chest, such as during turns.

To initiate a turn, the rider must use outriggers, such as a partial length of a ski attached to the lower end of a pole. Due to the rider's body position in a sit ski, and also due to the rider's own physical limitations in some cases, it is difficult to transfer weight to the edge of the ski to initiate a turn. Instead, the rider uses friction of the outrigger against the snow to rebalance the sit ski, create drag, or both to initiate and make a turn. An additional challenge of the sit ski, even for able-bodied riders, is that the body position makes it difficult to initiate a turn without the use of outriggers. The rider's center of gravity is over the ski, but the rider's upper body is behind the ski's center since the rider's legs and part of the seat extend forward. Since the rider is in a reclined or recumbent position with legs extending forward, it is difficult to one's body weight to set the ski on edge for turning. Further, since the rider is in a constrained position over the ski, the sit ski is inherently unstable and prone to tipping when not moving. For these reasons, riders of the sit ski generally consider outriggers to be an essential accessory.

Due to the challenges of the sit ski and of other available designs, a need exists for an improved support system that allows the rider to ride a snow sports board in a seated, forward-facing position. The present disclosure addresses this need and others. In accordance with some embodiments, the rider can sit on a seat mounted on top of the assembly. The rider's legs extend down with the knees somewhat bent along opposite sides of the support assembly's frame. In one example, the rider may place the knees on a platform or peg attached to the support frame. In another example, the rider may place the feet on a foot support attached to the board or on the board. In yet another example, the rider may ride in a seated position with the feet on the board below the seat. The riding position is generally comfortable and familiar to those who ride bicycles, motorcycles, or horses. Unlike a sit ski, the rider has enhanced control over the board and improved balance, due at least in part to the rider's athletic stance with a more upright and forward body position. Also unlike other assemblies, some support assemblies of the present disclosure elevate the rider above the board in a seated position that enables the rider to transfer weight to the board for turning. In accordance with some embodiments, the rider's seated position is akin to being seated at the edge of a seat with the ability of the rider to weight the feet (or knees) as needed to shift weight to the board and/or to balance.

While generally referred to herein as a support assembly for consistency and ease of understanding the present disclosure, the disclosed assembly is not limited to that specific terminology and alternatively can be referred to, for example, as a suspension assembly, a combined support and suspension assembly, a rider support assembly, a seated support system, or other terms.

Additionally, while referred to herein as a snow sports board, the disclosure is not limited to that specific terminology and alternatively can be referred to, for example, as a board, a snowboard, a ski, a runner, or other terminology. As will be further appreciated, the particular configuration (e.g., materials, dimensions, etc.) of assemblies configured as described herein may be varied, for example, depending on whether the target application is for recreational, competition, or specialized uses. Numerous configurations will be apparent in light of this disclosure.

Structure and Function

FIGS. 1-2 illustrate a front, top, and right-side perspective view and a top and left-side perspective view, respectively, of a binding and support assembly 50 shown mounted to a traditional snowboard or board 10 in accordance with an embodiment of the present disclosure. In one embodiment, binding and support assembly 50 includes a front assembly 100 and a rear assembly 200 configured to be secured to board 10. Binding and support assembly 50 is configured to support the rider on board 10 in a kneeling, face-forward position, where the rider's knees/shins are supported by front assembly 100. Rear assembly 200 is configured to support the rider's feet and/or ankles and can include a seat to support the rider in a seated position.

In embodiments, front assembly 100 and a rear assembly 200 are separate assemblies mounted to board 10 in a spaced-apart relationship, where front assembly 100 is mounted to forward portion 16 forward of midline 24 and rear assembly 200 is mounted to rearward portion 20 rearward of midline 24. For example, front assembly 100 is separate from and spaced from rear assembly 200. With the support assembly 50 extending across midline 24, the rider can shift weight forward or backward across midline 24 as needed to control board 10. In other embodiments, front assembly 100 and rear assembly 200 are connected by a common base plate or base structure extending across midline 24.

Board 10 has a top surface or deck 12, a bottom surface 14, a forward portion 16 with a tip 18, and a rearward portion 20 with a tail 21. The forward portion 16 generally includes portions of board 10 forward of a midline 24 and the rearward portion 20 includes portions of board 10 rearward of midline 24. Board 10 can be configured with edges 22 a, 22 b extending along the bottom surface at each lateral side. Board 10 can be configured as a freestyle snowboard, a racing snowboard, a ski, or other board 10. For example, board 10 has a length from 130 cm to 180 cm. Other lengths are acceptable. Some embodiments of the support assembly 50 of the present disclosure may be used with and attached to boards or other vehicles designed to traverse snow, water, sand, ice, dirt, grass, concrete, pavement, or other indoor or outdoor surface.

In some embodiments, the support assembly 50 attaches to deck 12 using fasteners extending through front and rear base plates and into pre-drilled, threaded holes (not visible) in board 10. For example, board 10 is a snowboard configured with threaded holes ready for attachment of snowboard bindings. In other embodiments, deck 12 is modified or prepared specially to receive fasteners in a pre-arranged pattern suited for the support assembly 50. For example, holes are drilled and tapped in a pattern that corresponds to fastener openings in components of the support assembly 50.

Referring now to FIGS. 3-4, a top and left-side perspective view and a left-side elevational view show front assembly 100 that includes a knee support 102, a riser 150, and a mounting plate 130 in accordance with an embodiment of the present disclosure. In one embodiment, knee support 102 includes a knee platform 106 configured to receive the rider's knees/shins. Knee platform 106 can be a flat plate or can be contoured for the rider's knees. Optionally, knee platform 106 includes sidewalls 108, such as left sidewall 108 a and right sidewall 108 b. Sidewalls 108 are useful to retain an optional knee pad 118 on knee platform 106. Knee pad 118 is provided for the rider's comfort and may be omitted or modified as desired. Sidewalls 108 also provide a point of attachment for calf strap 110 and a retention cord 111, for example. In one embodiment, a first strap portion 112 is secured to left sidewall 108 a and second strap portion 114 is secured to right sidewall 108 b. A strap fastener 116 can be used to tighten and retain calf strap 110 secured around the rider's calves. Strap fastener 116 can be secured to sidewall 108 in place of one of strap portions 112, 114. In other embodiments, strap fastener 116 is secured to calf strap 110 between first strap portion 112 and second strap portion 114. For example, strap fastener 116 is a ratchet-type fastener used with calf strap 110 having teeth. In some embodiments, knee support 102 is made of a rigid material, such as aluminum, steel, reinforced composites, fiberglass, or plastic.

In one embodiment, calf strap 110 includes a rigid plastic strap and buckle to secure the rider's calves to knee platform 106 when descending the ski slope in the kneeling position. Calf strap 110 allows the rider to lift the calf to help turn and stop board 10 by putting it on edge. Calf strap 110 is also useful to attach around one of the rider's heels to secure the rider's boot to knee support 102 without sliding off in the backwards direction when boarding and riding the chairlift. In some embodiments, for example, calf strap 110 is used together with toe clip 123 (shown in FIG. 1) to retain the rider's foot to knee support 102.

In some embodiments, knee support 102 is secured atop riser 150 to elevate knee support 102 above deck 12 for improved leverage in shifting the rider's weight to edges 22 a, 22 b of board 10. Riser 150 is used to secure knee support 102 to board 10 and raise the height of the rider above board 10 to provide more leverage to aid in turning by putting the board on edge. In some embodiments, riser 150 is configured to mate with 3-hole and/or 4-hole mounting patterns found on most snowboards available today.

In one embodiment, riser 150 can be a rectangular block, hollow horizontal tube, one or more vertical post, or other structure that is secured between knee platform 106 and board 10. In some embodiments, riser 150 comprises two or more shock absorbers disposed between deck 12 and knee platform 106. Riser 150 can be directly mounted to board 10 or may be secured to mounting plate 130. An advantage of using mounting plate 130 is that it facilitates longitudinal position adjustments for front assembly 100 along board 10 for riders of different sizes. Mounting plate 130 also facilitates easy attachment to riser 150 and to board 10 using separate fastener openings. In other embodiments, riser 150 is mounted directly to board 10 or includes mounting plate 130 as a single structure.

FIG. 5 illustrates a top plan view of an example mounting plate 130 in accordance with an embodiment of the present disclosure. Mounting plate 130 includes four bottom openings 131 recessed in a bottom surface for attachment to a bottom of riser 150. Four top openings 132 are recessed into top surface 133 for securing mounting plate 130 to board 10. Top openings 132 can correspond to a traditional four-hole pattern of snowboards on the market today or can be arranged in some other suitable pattern. Although top and bottom openings 131, 132 are shown as round through-openings with a recess for the fastener head, top and bottom openings 131, 132 can be slots. For example, mounting plate 130 optionally defines one or more slots along its center for adjusting the position of the knee support 102 along the X-axis (forward or backward along the board 10). Other numbers and placements of fastener openings and other configurations will be apparent in view of the present disclosure.

Referring now to FIG. 6, a left-side and front perspective view illustrates another embodiment of front assembly 100 that includes a knee support 102 attached to and vertically spaced from board 10 by riser 150. Knee support 102 is generally made of rigid materials, such as plastic, carbon fiber composite, fiberglass, metal, or combinations of these and other materials. Spacers 138 are attached with mounting screws directly to board 10 to provide torsional support with respect to riser assembly 150. Spacers 138 can be constructed of a resilient material to absorb vibration of board 10. In some embodiments, spacers 138 are made of a rubber block or the like, but could also be made of metal, plastic, or other rigid material.

Knee support 102 includes knee platform 106 that provides a flat or contoured surface upon which the rider places the knees and upper part of the shin. In one embodiment, knee platform 106 extends rearward toward rear assembly 200 and supports a major portion of the user's shin/tibia. In some embodiments, knee platform 106 has sidewalls 108 that extend along its edges to define a U-shape. Sidewalls 108 provide structural support to knee support 102 and aid in preventing twisting from torsional forces. Sidewalls 108 also define a surface against which the user's knee and leg can press while riding. Further, sidewalls 108 provide a point of attachment for a calf strap 110 and other accessories. In the embodiment shown in FIG. 6, calf strap 110 has first strap portion 112 secured to left sidewall 108 a and second strap portion 114 secured to right sidewall 108 b, where first and second strap portions 112, 114 releasably connect to each other using strap fastener 116. Strap fastener 116 can be, for example, a snap buckle, pair of D-rings, ratchet lever and geared strap, hook-and-loop fastener, or some other suitable fastener. Strap fastener 116 allows the user to adjust the length of calf strap 110 to tighten calf strap 110 over the lower legs to retain the rider on front assembly 100.

Optionally, knee support 102 includes a front portion 120 that connects to and extends between sidewalls 108 of knee platform 106. In one embodiment, front portion 120 is a curved plate or bar that extends around the front of the knee platform 106. In one embodiment, front portion 120 includes rounded corner portions 124 connected by a cross piece 126 extending laterally between them. Front portion 120 optionally includes a leg-support portion 128 that extends upward from crosspiece 126. Leg-support portion 128 is constructed to contact the rider's thighs when the rider leans forward in a high kneeling position. When the rider changes to a high kneeling position with the thighs against leg-support portion 128, the rider may brace against leg-support portion 128 to transfer weight to board 10 and load an edge 22 a, 22 b of board 10 to initiate turns. In the high kneeling position, the rider is positioned to absorb bumps and impact by bending at the waist and knees. Leg-support portion 128 also allows the rider to assume the high kneeling position without falling forward. Further, moving between the low kneeling position and the high kneeling position allows the user to maintain balance and/or assume a strategic position for traversing certain terrain by pushing forward against board 10 when using a pole, a paddle, or the hands to dig into the snow for propulsion. Leg-support portion 128 also provides some protection to the rider from snow, shrubs, or debris on the mountain.

In one embodiment, front portion 120 defines a forward toe opening 122 that is positioned vertically between knee platform 106 and front portion 120. Forward toe opening 122 is sized to receive the toe of a boot or shoe. As such, corner portions 124 and cross piece 126 of knee support 102 prevent the rider's knees from sliding forward off knee platform 106 during use. Knee support 102 is also constructed as such to provide a foot hold to allow riders to ride the chairlift with the toe of one of the rider's boots extending through toe opening 122. In other embodiments, toe opening 122 is provided by a toe clip 123 or the like attached to knee platform 106 and positioned to receive the rider's boot. As shown for example in FIG. 1, toe clip 123 similar to those used in bicycling is secured to knee platform 106 and provides toe opening 122.

In one embodiment, leg-support portion 128 has an adjustable position relative to crosspiece 126. For example, leg-support portion 128 has an adjustable canting device to change the angle between leg-support portion 128 and knee platform 106. As such, the rider can tilt or pivot leg-support portion 128 forward or backward to increase or decrease the intensity of the forward energy transfer and therefore the responsiveness of board 10. Optionally, leg support portion 128 defines openings 129 that may be used for an additional thigh strap extending around the rider's thighs to secure leg-support portion 128 to the rider. This same thigh strap can be used to extend around the rider's lower leg when the rider's toe is in the forward toe opening 122 when riding chairlifts. Openings 129 may also be used as hand holds when the rider is in a kneeling position or when carrying board 10. Openings 129 may further be used to connect a retention cord 111 (shown in FIGS. 3-4) or the like to board 10.

Crosspiece 126 and leg-support portion 128 may be one monolithic structure with a permanent, fixed position for leg-support portion 128. Alternately, crosspiece 126 and leg-support portion 128 may be a plurality of individual components that are attached together as part of knee support 102. Similarly, knee support 102 can be a single monolithic structure in some embodiments and a group of separate components in other embodiments. Knee platform 106 may have a flat surface or a contoured surface shaped for one's knees. Optionally, knee support 102 is padded for comfort. Optionally, the knee platform 106 includes a short wall, ridge, or partition (not shown) that extends longitudinally along knee platform 106 between the rider's knees.

In one embodiment, knee support 102 is attached to board 10 with fasteners 104 (e.g., screws) that extend through knee platform 106 and riser 150. In some embodiments, riser 150 is omitted and knee support 102 attaches directly to board 10. In yet other embodiments, riser 150 is formed as part of the knee support 102. In still other embodiments, riser 150 is a separate assembly that is secured to the bottom of the knee platform 106, where attaching knee support 102 to board 10 involves securing knee support 102 and riser 150 as an assembled group to board 10.

Referring now to FIG. 7, a top and left-side perspective view illustrates rear assembly 200 with foot support 210 and seat 250 in accordance with an embodiment of the present disclosure. Rear assembly 200 includes a base 230 that includes a base plate 232 and riser tube 226 attached to base plate 232 and extending upward therefrom. In some embodiments, riser tube 226 extends vertically from base plate 232. In other embodiments, riser tube 226 can extend upward at an angle α of less than 90° as defined between riser tube 226 and board 10 in front of riser tube 226. In some embodiments, a stay 236 extends between base plate 232 and an upper end portion 226 a of riser tube 226. For example, stay 236 substantially defines a triangle with riser tube 226 and base plate 232. Stay 236 provides structural support to riser tube 226, especially when rear assembly 200 is equipped with seat 250 constructed to bear weight of the rider. Stay 236 can include a plate, one or more bars, one or more tubes, or other rigid structure(s) between base plate 232 and riser tube 226. Numerous configurations will be apparent in light of the present disclosure.

In some embodiments, base plate 232 includes one or more plates. For example, base plate includes a first base plate 232 a that connects to riser tube 226, stay 236, and post clamp 238 using fasteners extending upward through the bottom of first base plate 232 a. A second base plate 232 b is secured to board 10 by fasteners extending through a top surface. First base plate 232 a can then be secured to second base plate 232 b using fasteners extending through first base plate 232 a and into second base plate 232 b and optionally also extending into board 10. The use of first base plate 232 a and second base plate 232 b provides an adjustable position of rear assembly 200 along second base plate 232 b.

In one embodiment, riser tube 226 is a hollow tube constructed to receive a seat post 252 of seat 250. For example, riser tube 226 includes a flanged lower end 226 b that can be secured to base plate 232 using a post clamp 238 installed around riser tube 226 and attached to base plate 232 with fasteners. For example, riser tube 226 extends upward through the post opening 233 of lower post clamp 238 with the flange engaging the bottom surface of first base plate 232. In one embodiment, post clamp 238 defines a slot 239 to post opening 233, where slot 239 can be drawn together using a fastener to tighten post clamp 238 to riser tube 226. Upper end portion 226 a of riser tube 226 similarly can include post clamp 238 for attachment of stay 236. For example, post clamp 238 on upper end portion 226 a slidably receives riser tube 226 therethrough and can be tightened on riser tube 226 at a position appropriate to attach to stay 236. In some embodiments, for example, riser tube 226 can be longer than as shown in FIG. 7, where post clamp 238 is positioned towards upper end portion 226 a along the length of riser tube 226.

In some embodiments, riser tube 226 is constructed as a piston or shock absorber with seat post 252. For example, riser tube 226 contains a spring, gas piston, or other resilient and compressible structure disposed between the end of seat post 252 and lower end 226 b of riser tube or base plate 232.

Horizontal support bar 214 is attached to base 230 and extends laterally with left end portion 214 a and right end portion 214 b positioned to support the rider's feet/ankles. Horizontal support bar 214 can be secured to stay 236 or to riser tube 226. Optionally, horizontal support bar 214 is omitted and replaced by angled footholds 215 (shown in FIG. 18) attached to board 10 or to base plate 232. In yet other embodiments, foot supports or footholds 215 can be used in addition to horizontal support bar 214. For example, rear assembly 200 includes footholds in the shape of a wedge, a strap, a block, tred, or other structure that provides purchase for the rider's feet in the kneeling or sitting position.

In some embodiments, ankle strap 216 is connected to left end portion 214 a and right end portion 214 b of horizontal support bar 214. Ankle strap 216 can be used to releasably hold the rider's feet or ankles against horizontal support bar 214 and/or maintain the rider's toes against the board 10. The rider can also use ankle strap 216 and calf strap 110 (shown in FIGS. 1-4) to lift part of board 10 (e.g., one edge 22) from the snow as the rider leans to one side or the other.

Referring now to FIG. 8, a top, front, and left-side perspective view shows base 230 of FIG. 7. Riser tube 226 extends up from base plate 232 and is secured by lower post clamp 238 b. Lower post clamp 238 b is fixed to base plate 232 by fasteners 240 extending up through base plate 232 into lower post clamp 238 b. Base plate defines recessed mounting openings 241 Stay 236 is attached between base plate 232 and upper post clamp 238 a using fasteners. Stay 236 defines a plurality of mounting openings 241 for attachment of horizontal support bar 214 with an adjustable vertical position. Stay also defines an access opening 242 to facilitate access to fasteners secured through mounting openings 241.

FIGS. 9 and 10 illustrate top plan views of first base plate 232 a and second base plate 232 b, respectively. First base plate 232 a defines mounting openings 241 recessed into a top surface and corresponding to openings 243 in second base plate 232 b. Openings 244, 245 are recessed into a bottom surface and correspond to lower post clamp 238 b and to stay 236, respectively. Second base plate 232 b defines a plurality of openings 246 recessed into a top surface for securing second base plate 232 b to board 10. Based on the rider's height, first and second base plates 232 a, 232 b may be secured to board 10 and to each other as needed to provide spacing from front assembly 100 suitable to the rider.

Referring now to FIG. 11, a top and front perspective view illustrates seat 250 in accordance with an embodiment of the present disclosure. Seat 250 includes a seat platform 254 secured to seat post 252, where seat platform 254 is constructed to support the rider in a sitting position. Seat platform 254 can be flat or contoured for comfort. Optionally, seat platform 254 is padded. In some embodiments, seat platform 254 includes side plates 256 extending up to provide a lateral restraint for the rider's hips. Side plates 256 also can facilitate transferring the rider's weight to board 10 for initiating turns. Seat post 252 has a length suitable to support the rider in a seated position. Seat post 252 is received in riser tube 226. In some embodiments, the height of seat platform 254 above board 10 is adjustable by changing the length of seat post 252 received in riser tube 226 and using upper post clamp 238 to secure its position. In one embodiment, seat platform 254 is tilted forward (also shown in FIG. 2) consistent with the position and angle of the rider in a forward-facing, kneeling position.

Referring now to FIGS. 12 and 13, top and bottom views, respectively, illustrate ankle cups 270 in accordance with an embodiment of the present disclosure. FIG. 12 shows a pair of ankle cups 270 attached to horizontal support bar 214. Fasteners 271 extend through horizontal support bar 214 for attachment to stay 236 or other component of base 230. FIG. 13 shows a bottom view of ankle cup 270 with openings 272 for horizontal support bar 214. In one embodiment, horizontal support bar 214 extends through openings 272. As such, ankle cups 270 are secured, yet can rotate as needed to align with the rider's ankle.

Referring now to FIG. 14, a front and left-side perspective view illustrates another embodiment of rear assembly 200 in accordance with the present disclosure. In this embodiment, seat 250 is omitted and foot support 210 includes an adjustable vertical tube 212 connected to a horizontal support bar 214 in a T shape. Vertical tube 212 is slidably received in riser tube 226. For example, rear assembly 200 includes footholds 215 (shown in FIG. 18). In another example, rear assembly 200 includes ankle cups 270 as illustrated in FIGS. 12-13. In some embodiments, rear assembly 200 includes both footholds 215 and ankle cups 270 or horizontal support bar 214. In any of these embodiments of rear assembly 200, ankle strap 216 and/or additional strap 218 can be included or excluded.

As with embodiments discussed above, riser tube 226 extends vertically from base 230 configured to be attached to rearward portion 20 of board 10. In this embodiment, base 230 includes base plate 232 and a gasket or interface plate 234 disposed against board 10. Interface plate 234 can be made of resilient or rigid materials including rubber, plastic, and metal.

Horizontal support bar 214 is spaced vertically above board 10. Riser tube 226 is secured to base plate 232 using lower post clamp 238 b, which is also secured to base plate 232. In other embodiments, vertical tube 212 is fixedly attached to horizontal support bar 214, such as by welding. In other embodiments, horizontal support bar 214 extends through the vertical tube 212 with its position secured by fasteners.

In one embodiment, the distance above board 10 is adjustable by telescoping vertical tube 212 into or out of riser tube 226 and locking its position using upper post clamp 238 a, fasteners, or other suitable structure. Some riders may prefer to raise horizontal support bar 214 so that the toes do not touch the board 10, thereby putting the rider's weight on the heel & ankles instead of the toes. Other riders may want to have the toes touching the snowboard so that the rider can push off or brace with the toes to help the rider control the snowboard and shift weight.

Ankle strap 216 is connected to opposite ends of horizontal support bar 214 for securing the rider's feet and ankles to rear assembly 200. An optional second strap 218 is oriented approximately 90° to ankle strap 216 as viewed from the side and also connects to and extends between opposite ends of the horizontal support bar 214. In one example, ankle strap 216 can be secured around the bottom of the rider's boots and second strap 218 can be secured around the rider's waist or legs. Numerous variations, configurations, and other embodiments will be apparent from the present disclosure.

Referring now to FIG. 15, a pole 300 is illustrated in accordance with an embodiment of the present disclosure. Pole 300 extends longitudinally from a first end portion 302 to a second end portion 304. In other embodiments, each end portion 302, 304 defines a notch or tip 303 to engage the snow. For example, pole 300 has a tip 303 extending axially from each end portion 302, 304 to engage packed snow. Optionally, each tip 303 includes a basket to prevent tip 303 from extending too far into the snow and to reduce the likelihood of pole 300 freely sliding down a slope. Optionally end portions 302, 304 may include paddle blades so that a two-bladed paddle can be used in powder, to paddle across flat terrain, or to assist in steering and balance. Pole 300 can be made of carbon fiber composite, PVC, fiberglass, aluminum, steel, or other suitable material. In one embodiment, pole 300 has an outer diameter from about 30 mm to 35 mm and a length of about 1.4 m to 1.7 m. Other diameters and lengths are acceptable.

Referring now to FIG. 16, a side elevational view shows an example of a support assembly 50 in accordance with yet another embodiment of the present disclosure. As with embodiments discussed above, front assembly 100 includes knee support 102 on riser 150 secured to forward portion 16 of board 10. Rear assembly 200 includes base plate 232 with vertical tube 212 extending to horizontal support bar 214. Seat post 252 of seat 250 extends forward to riser 150 of front assembly 100 and is pivotably attached. Although seat post 252 is illustrates as having a concave curvature, seat post 252 can alternately be straight or have a convex curvature. In one example, seat post 252 has a concave curvature to provide additional clearance for a chairlift seat to fit below seat 250.

In one embodiment, seat post 252 connects to and rotates about a shaft 151 extending laterally through riser 150. Stay 236 extends from seat post 252 rearward and downward to base plate 232 of rear assembly 200. Stay 236 can be constructed to include a shock absorber 280 extending between seat 250 (or seat post 252) and base 230. In some embodiments, stay 236 has an adjustable length to raise or lower seat 250 from board 10. Additionally, shock absorber 280 can be adjusted for a softer or stiffer ride. In some embodiments as shown in FIG. 17, for example, knee platform 106 can be modified to define an opening 103 for clearance of seat post 252 as seat 250 pivots up and down. In some embodiments, seat 250 includes side plates 256 (shown in FIG. 11). In some embodiments, a waist strap or seatbelt (not shown) can be used with seat 250 to retain the rider to the seat. Such an embodiment can be particularly useful for disabled riders. Although not shown in FIG. 16, front assembly 100 and rear assembly 200 can include calf strap 110, ankle strap 216, ankle cups 270, and other components discussed herein. Optional footholds 215 (shown in FIG. 18) can be attached to rearward portion 20 of board 10. Footholds 215 can be separate from rear assembly 200. In other embodiments, footholds 215 can be secured to base plate 232.

FIG. 18 illustrates a side view of an example of a rider 400 using a support assembly 50 with board 10 and pole 300 in accordance with an embodiment of the present disclosure, where the rider is in a forward-facing, kneeling and seated position. Rider 400 has knees 402 on front assembly 100 and secured with calf strap 110 extending over the rider's calves. The rider's ankles 404 are supported by rear assembly 200 and secured with ankle strap 216. The rider's feet 406 are positioned against footholds 215. The rider 400 is seated on seat 250, which includes a shock absorber 280. The rider 400 uses pole 300 for balance and to assist in navigating terrain. When the support assembly 50 is installed across the midline 24 (shown in FIGS. 1-2) of board 10, the rider's center of gravity may be shifted behind, even with, or forward of midline 24 to transfer weight longitudinally along board 10. The rider can shift weight laterally, such as by leaning, to set board 10 on an edge 22 a, 22 b to initiate turns.

In use, the rider places his knees on the knee support 102 of front assembly 100 and rests his feet/ankles on the rear assembly 200, such as on horizontal support bar 214. After securing straps 110, 216 to hold the rider firmly to the board 10, the rider may shift between a low kneeling and/or seated position and a high kneeling position. In embodiments with the leg-support portion 128, the rider can press forward against the leg-support portion 128, tilt to either side, or lean backward to maneuver the board 10. In embodiments equipped with seat 250, the rider may ride in a seated position (shown, e.g., in FIG. 18) with the knees on front assembly 100. With seat 250, the rider can transition between a seated position, a low kneeling position, and a high kneeling position as needed to traverse terrain and absorb bumps. Optionally, the user can employ pole 300 for improved balance and to facilitate turning by dragging or pushing pole 300 against the snow.

When riding a chairlift, for example, the rider can use toe opening 122 to attach board 10 to the rider's foot. For example, the rider completely un-clips from the support assembly 50 (which may include front assembly 100 and rear assembly 200), stands up, and slides the toe of one boot through the forward toe opening 122 on knee support 102. The toe clip 123 or toe opening 122 in front portion 120 will hold the rider's foot from moving forward or upward. Calf strap 110 can be fastened around the heel of the rider's boot to secure the boot to front assembly 100 (and therefore the board 10). With front assembly 100 holding the rider's foot forward in toe opening 122, the rider can ride a chairlift in the same manner as done with a traditional snowboard binding where the rider's front foot being secured to the snowboard by the front binding.

FIG. 19 illustrates a side view of a support assembly 50 that includes a suspension assembly 300, in accordance with an embodiment of the present disclosure. In some embodiments, the suspension assembly 300 includes a base 310 configured to be mounted to a snow sports board 10 (or simply “board”). In some embodiments, the base 310 has a length L comparable to that of a ski boot, snowboarding boot, or binding thereof. In some such embodiments, the base 310 is mounted over a center C of the snow sports board 10 so that the turning performance of the board 10 uses the same or similar portion of the board 10 and the weight of the rider is also generally centered over the board 10 during use. The base 310 includes a rear base portion 312 and a front base portion 314. As shown in FIG. 19, the rear base portion 312 and front base portion 314 can be connected or integrally made as a single component of the suspension assembly 300. In one example embodiment, the base 310 can be fastened to the board 10 using screws received in threaded holes in the board 10.

A shock absorber 330 has a lower end 332 attached to the front base portion 314. For example, the lower end 332 is bolted to the base 310 so that the shock absorber 330 can pivot about the bolt. An upper end 334 of the shock absorber 330 is pivotably attached to a frame 350. For example, the upper end 334 is bolted or otherwise secured to a body 352 of the frame 350. In some embodiments, the shock absorber 330 has a generally upright orientation, including defining an angle α with the board 10 with a range from 60-130°, including 80-100° and 70-110°, for example. In some embodiments, the shock absorber 330 is tilted forward at an angle from 60-90°, including 70-85° and 80-88°. The shock absorber 330 can be a pneumatic piston with a spring, a hydraulic piston with a spring, a spring shock absorber, or other shock absorber designed to absorb and damp shock impulses, such as bumps in the terrain or landing impact when riding the board 10. For example, the shock absorber 330 includes a piston 336 that is slidably received in a cylinder 338.

In accordance with one embodiment, the frame 350 includes a first portion 354 extending downwardly and a second portion 356 extending rearwardly from the first portion 354. In some embodiments, the frame 350 defines a body 352 between the first portion 354 and the second portion 356 of the frame 350. For example, the first portion 354, second portion 356, and body 352 generally define an inverted L shape, where the body 352 is located at a corner between the first and second portions 354, 356. The frame 350 can be connected to and supported at least in part by the shock absorber 330. In one embodiment, the body 352 is generally hollow and is attached to the upper end 334 of the shock absorber 330, which is received between lateral portions of the body 352. In one embodiment, the body 352 is made of metal and has a cross-sectional shape of a U, a rectangle, a circle or oval, a triangle, or other open or closed shape, as will be appreciated. In embodiments having a U-shaped cross-sectional shape, the body 352 may include a front panel 352 a and opposed side panels 352 b, where the upper end 334 of the shock absorber 330 is received between the opposed side panels 352 b. The rear portion of the body 352 is open to permit the body 352 to pivot relative to the shock absorber 330.

In one embodiment, the first portion 354 of the frame 350 extends downwardly from the body 352 along the front and/or side portions. In some embodiments, the first portion 354 is continuous with and integral to the body 352. In other embodiments, the first portion 354 is a separate part that can be attached to the body 354. The first portion 354 can be configured with a mounting bracket 360 for a knee support platform, such as knee support 420. For example, the mounting bracket 360 is a tab or protrusion that extends generally horizontally and defines openings for fasteners. In some embodiments, the frame 350 includes two or more mounting brackets 360 along each side. The height of the knee support 420 above the board 10 and the vertical distance between the knee support 420 and the seat 390 can be modified by selecting the appropriate mounting location, as will be appreciated. Alternately, the frame may not specifically define mounting brackets 360, but instead defines mounting openings to define one or more locations to attach knee support 420. In one embodiment, the mounting bracket 360 permits adjustable tilt of the knee support 420. For example, a rearward end of plates 421 of the knee support 420 has an adjustable height above the board 10, thereby permitting the rider 500 to adjust the angle of the plate(s) 421 with respect to the board 10. In some such embodiments, the rider 500 may desire to release the rearward end of the plate(s) 421 for boarding a chairlift, such as by releasing a catch on the mounting bracket 360. When the rider 500 is ready to ride, the rearward end of the plate(s) 421 can then be raised and locked in place by re-engaging the catch on the mounting bracket 360. Numerous variations and embodiments will be apparent in light of the present disclosure.

The second portion 356 of the frame 350 defines a support or seat beam that extends along a bottom of a seat 390, in accordance with some embodiments. The second portion 356 has a forward end portion 356 a and a rearward end portion 356 b. For example, the second portion 356 is configured as a cantilever that extends rearwardly over the board 10 a distance of 16-20 inches, and provides cantilevered support to the seat 390. In some embodiments, the second portion 356 can be continuous with and integral to the body 352. In other embodiments, the second portion 356 of the frame 350 can be a separate component that is attached to the body. In one example embodiment, the forward end portion 356 a of the second portion 356 of the frame 350 can be removably attached to the body 352 using bolts or other suitable fastener. In some embodiments, the second portion 356 of the frame 350 defines an open region 380 below the seat 390 that is configured and sized to receive the seat of a chairlift or equivalent.

In some example embodiments, the second portion 356 of the frame 350 is elevated above each knee plate 421 by about 6-9 inches, such as about 7.5 inches. In one such embodiment, the rearward end portion 356 b of the second portion 356 of the frame 350 is about 16 inches or more above the ground to provide clearance to receive a chairlift seat 602 when no rider is on the assembly. The second portion 356 extends about 15 inches from the first portion 354 of the frame. For example, the open region 380 has a length from the rearward end portion 356 b to the body 352 of the frame 350 of about 12 to 18 inches, including the subrange of 14-16 inches, about 15 inches, or other suitable length comparable to or appropriate for the size of a chairlift seat 602.

In some embodiments, the second portion 356 of the body 352 has a height above the board 10 sufficient to receive the chairlift seat 602 below it when the shock absorber is in an active-use state. For example, chairlift seats may be between 16 and 22 inches above the ground. Accordingly, in some embodiments, the bottom of the second portion 356 is at least that height above the ground when the suspension assembly 300 is mounted to a board 10. In other embodiments, the rearward end of the second portion of the frame is at least 16 inches above the board 10, such as from 16 to 22 inches above the board 10, including 16-18 inches, 16-20 inches, 18-20 inches, and 18-22 inches. When the rider is seated on the seat 390 in a resting or stationary position for the board 10, the shock absorber typically will compress to some extent, referred to as sag. Accordingly, in some embodiments, the rearward end portion 356 b of the second portion 356 of the frame 350 is from 16 to 22 inches above the board 10, inclusive of sag in an amount up to 3 inches (e.g., 1-3 inches), up to 4 inches (e.g., 2-4 inches), or up to 5 inches (e.g., 2-5 inches) of sag when the rider is seated on the seat 390 and/or kneeling on the knee support 420. Numerous variations and embodiments will be apparent in light of the present disclosure.

A first linkage 370 connects the body 352 to the rear base portion 312. A second linkage 372 connects the bottom end 355 of the frame 350 to the front base portion 314. The first linkage 370 and second linkage 372 extend between the frame 350 and the base 310 to provide torsional stability and limit the range of motion of the seat 390 in response to compressing or extending the shock absorber 330. In one example, the first linkage 370 extends upward and forward at an angle of about 45° from the base 310 to the frame body 352 and attaches adjacent the upper end 334 of the shock absorber 330. The second linkage 372 extends upward and forward to the bottom end 355 of the frame 350 at an angle of about 60°. In one embodiment, each of the first linkage 370 and the second linkage 372 can include a pair of rods extending in parallel. For torsional stability, the rods can be connected along much of their lengths by a plate to approximately define an H shape. In other embodiments, the first linkage 370 and the second linkage 372 include a single rod that connects to the frame 350 and the base 310 at a single point or at two points using a yoke or forked end, for example. Numerous variations and embodiments will be apparent in light of the present disclosure.

FIG. 20 illustrates a side view of the suspension assembly 300 of FIG. 19, showing the shock absorber 330 in a compressed state as the result of a downward load applied to the seat 390. The first linkage 370 and second linkage 372 resist twisting and leaning of the suspension assembly 300 with respect to the base 310. The first and second linkages 370, 372 also substantially limit movement of the seat 390 to be forward-backwards or up-down along a vertical plane extending upward from the board 10 (rather than laterally or torsionally with respect to the board) when the shock absorber 330 is compressed or extended. That is, when a downward load is applied to the seat 390, the frame pivots about the upper end 334 of the shock absorber 330. The second linkage 372 limits upward movement of the first portion 354 of the frame 350 when the frame 350 pivots about the upper end 334 of the shock absorber 330 during compression of the shock absorber 330. As such, a downward force on the seat 390 compresses the shock absorber 330 with the second portion 356 of the body 352 acting as a lever handle. For example, a downward force on the seat 390, such as the rider's weight, compresses the shock absorber 330 and pivots the frame 350 downward and forward about the upper end 334 of the shock absorber 330 so that the downwardly-extending first portion 354 of the frame pivots forward. Since movement of the frame 350 is restricted by the first and second linkages 370, 372, the first portion 354 of the frame 350 tends to rotate forward when the shock absorber 330 is compressed downward along the axis of the shock absorber 330. For example, a downward force on the seat 390 causes the seat to translate downward along the path of the shock absorber 330 while also rotating about the connection at the upper end 334 of the shock absorber 330. Such action substantially maintains the weight of the rider over the center C of the board 10, in accordance with some embodiments.

The frame 350 and seat 390 can be constructed to have a narrow, moderate, or relatively wide size between the rider's knees. In a kneeling position on the knee support 420, a wider spacing between the knees provides a stable stance from which the rider can balance and control the board 10, as will be appreciated. When sitting on the seat 390, the rider may squeeze the frame 350 between the knees for control and stability. For example, the frame 350 has a lateral width (between side panels 352 b or measured as seat width) from 4 to 16″ or other suitable width. In some embodiments, the rider's knees 502 are spaced by the frame 350 and/or seat 390 having a lateral thickness of at least 4″, including at least 6″, at least 8″, at least 10″, at least 12″, or at least 14″. In other embodiments, the frame 350 and/or seat 390 has a lateral thickness between the rider's knees 502 from 4-12″, 4-8″, 6-10″, 6-12″, 8-12″, or 8-16″. Numerous variations and embodiments will be apparent in light of the present disclosure. The rider's feet 504 may be positioned close together, approximately defining a tripod stance with the knees 502, or spaced apart to define a four-point stance with the knees 302.

Referring now to FIG. 21, a side view illustrates the support assembly 50 of FIG. 19 with the addition of a knee support 420 secured to the second portion 354 of the frame 350. In one embodiment, the knee support 420 includes left and right plates 421 that connect to the frame 350 using the mounting brackets 360. The plates of the knee support 420 can be sized to accommodate the rider's knee and/or shin, for example. In other embodiments, the knee support 420 is a peg or bar that extends laterally from the frame 350. In some such embodiments, the rider may use a shin guard 440 or other accessory to distribute the rider's weight on the relatively small area of the peg. In some embodiments, the knee support 420 has a fixed position and extends laterally from the frame 350. In other embodiments, the knee support 420 can be folded up along the side panels 352 b of the body 350. Thus, when not in use, such as when the rider prepares to board a chairlift or when the support assembly 50 is being transported, the plates 421 can be folded up along the face of each side panel 352 b. Embodiments of the suspension assembly 300 with the knee support 420 can include or omit the foot support 400.

The embodiment of FIG. 21 also includes an optional foot support 400. In some embodiments, the foot support 400 includes lateral bars that are configured to contact the top or front of the rider's ankles, such as when the rider's toes tuck behind the bars. In another embodiment, the foot support 400 can be configured to contact the soles of the rider's boots, such as at the toe region, middle region, or heel region. In some embodiments as shown, the foot support is separate from the suspension assembly 300.

FIG. 22 illustrates a side view showing an example riding position for the suspension assembly 300 of FIG. 19, in accordance with some embodiments.

Plates 421 are connected to opposite sides of the frame 350, providing a support platform for each of the rider's knees 502 and lower legs 508.

FIG. 31 illustrates a rear view of a support assembly 50 configured with a suspension assembly 300, seat 390, and knee support 440, in accordance with an embodiment of the present disclosure. In this example, each plate 421 includes a shin guard 440 that is shaped to conform to the rider's lower leg 508. The shin guard 440 is secured to the plate 421 in some embodiments. As can be seen in FIG. 31, the width of the seat 590 and the knee support 420 extends laterally beyond the board 10. When using the optional foot support 400, the rider 500 can achieve a tripod-like stance with the knees 502 extending over the sides of the board 10 and the feet 504 engaging the foot support 400, which is secured along the center of the board 10. The rider 500 can use these features for balance and to transfer weight to edges of the board 10 for turning.

In use, a support assembly 50 as variously described herein can provide a way to traverse packed or loose snow in a way that is different from both skiing and snowboarding. In accordance with some embodiments, the support assembly 50 provides a seat 390 with hip plates 394 or other barrier the rider 500 can use to transfer weight to the board 10. For example, when the rider 500 leans the torso to one side of the board 10, the rider 500 leans against the hip plates 394 and/or a waist strap 432, thereby transferring weight to the edge of the board 10 for turning. In accordance with some embodiments, a knee support 420 can be shaped to restrain the rider's lower leg 508 from sliding off of the plate 421. For example, the knee support 420 includes shin guards 440, a plate 421 with a concave shape, a knee plate 421 with sides 422, or a combination of such features. By engaging one or more of these features with the rider's lower leg 508, the rider 500 can efficiently shift weight to the board 10 for turning and control, for example. The combination of a seat 390 with hip plates 394 and a contoured knee support 420 can eliminate the need to secure the rider's ankles/feet 504 and lower leg 508, in accordance with some embodiments. Instead the rider 500 can use only a waist strap 432 to secure the rider 500 to the support assembly 50. Numerous variations and embodiments will be apparent in light of the present disclosure.
